MACHINE FOR ATTACHING TOGETHER PARTSOF Boers AND'SHOES;

Application filed March 28, 1923. Serial No. 628,242.

To all whom it may concern:

Be it known that I, JosErH FAUssE a citizen of the United States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented certain Improvements in Machines for Attaching Together Parts of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like-parts in the several figures.

This invention relates to machines for securing together parts of boots and shoes, the illustrated embodiment of the invention being particularly adapted for use in securing shank pieces in turn shoes.

The rear portions of turn shoes are constructed in a variety of ways. In making turn shoes of the kind known as sewed seat turns, the seam which attaches the upper 'to the sole about the periphery of the shoe from breast line to breast line is extended about the heel-seatalso to attach the lining,

counter, and upper to the sole at the rear portion of the shoe. After such a shoe has been turned right side out, a shank piece is placed inside the shoe to cover the seam about the heel-seat and usually extends along the shank at least to the break line or ball line. To this shank piece is usually secured a shank stiffener by which the proper de gree of stiffness is given to the shank portion of the sole.

Other kinds of turn shoes are made with molded counters according to methods such, for instance, as those disclosed in United States Letters Patent to Helming No. 1,177 516, granted March 28, 1916, and in United States Letters Patent to Toothaker No. 1',- 368,373, granted February 1-5, 1921. Such shoes also require the insertion of shank pieces similar to those employed in sewed seat turn shoes. It is a common practice to insert and secure the shank pieces of turn shoes entirely by hand.

Objects of the present invention are to provide mechanism by the use of which shank pieces may be quickly and conveniently inserted and secured in turn shoes of various kinds, and by the use of which proper pres- 7 during this securing operation.

sure may be applied to hold the sole, shank piece, and the intervening parts together Features of the invention consist in the provision of means for applying upward pressure to the shoe bottom, together with fastening inserting means normally in a forward positionto permit the shoelto be placed over it and movable rearwardly with the shoe to a position over the'pressu're applying shoe and fastening mechanism toward the pressure applying means. The shank piece holding means may comprise spring clips the ends of which are turned inwardly to engage under the shank piece, the clips being arranged to yield vertically when the pres-V I sure is applied.

In order to locate the shoe properly with respect to the shank piece, there is provided a device to engage the rear end of the shoe as the shoe and the shank piece are moved rearwardly, the device causing movement of the shoe to be arrested so that the shank piece may be pushed into its proper position at the rear end of the shoe. The device is preferably arranged, as shown, to yield to rearward'pressure of the shoe after -the shank piece has been brought into proper relation to the shoe. I

These and other features of the invention, including novel constructions and arrangements of parts, will appear more fully from the following detailed description when read in connection with the accompanying drawings and will be pointed out in the appended claims."

Fig. 6 is a sectional detail of parts shown in Fig. 2.

Referring to Fig. 1 of the drawings, the machine comprises a frame or column 2 upon'the front side of which is arranged a vertically movable presser or support 4 for applying upward pressure to the shoe. The presser is mounted on the upper end'of a 'rod 6 arranged to slide longitudinally in bearings 8 and. 10 on the ,frame 2. To the lower end of the rod is pivoted a link 12 which is also pivoted on an arm 14 of an angle lever pivoted at 16 to the frame, the other arm 18 of the lever being formed as a treadle. The link 12 and the arm 14 constitute a toggle which may be straightened by depression o-f the treadle to cause the rod 6 and the presser 4 to be raised. The bent position of the toggle, and hence the lower position of the presser 4,. is limited by a stop screw 20 threaded through the frame in' position to be engaged by the toggle near its joint when in broken position, in which position it is normally held bya spring 22 connected between the frame and the arm 14. p

In vertical alinement with the presser 4 is a shaft 24 mounted in bearings on the frame 2. 7 Upon the shaft 24 a member26, forming the casing of the fastening inserting mechanism, is arranged to swing from the position shown in Fig. 1 to a position in vertical alinement with the presser 4 and is held normally in the position shown by a coil spring 28 of the torsion type, one end of which is fixed and the other end arranged to engage a pin 30 on the fastening inserting means. vAt 31 are engaging faces formed respectively on theframe 2 and on thecasing 26 by which outward swinging movement of the casing under the influence of the spring 28 is limited. Within the casing 26 is arranged a plunger 32 which is normally sustained by a spring 34. Upon the lower end of the plunger is a head 36 to which are secured three drivers 38 by which three tacks may be driven simultaneously. Uponthe upper end of the plunger 32 is a roll 40 which is arranged to be engaged by a suitable cam 42 fixed to the shaft 24. The shaft 24 carries loosely a pulley 44 and between the pulley and the shaft is arranged a suitable one-revolution clutch to cause a single revolution to be imparted to the cam 42 when desired. be tripped by downward movement of a link 46 which is connected to one arm 47 of an angle lever pivoted to the frame: at 48 and having on its other arm a handle 50 arranged ina convenient position for manipulation by the operator to set the clutch and cause a single revolution to be given to'the cam 42 and hence a single driving stroke to the plunger 32. The lower end of the casing 26 is provided with a driver block 51 having passages 37 in which the drivers 38 are located. Tack tubes 52 are arranged to convey tacks into ducts leading into the driver passages below the drivers. The upper parts 53 of the tubes 52 are vflexible to permit swinging movement of the casing 26. 'Tiaclrs are supplied to the tubes 52 in any'convenient manner, for instance, from a tack pot by raceways and separators of the usual type, as indicated at 57 in Fig. 1.

To hold the tacks fed to the driver passages in position to be driven and to prevent their falling out, the tack holding mechanism shown in Figs. 3 and 4' is provided; Two members 54 and 56 are secured by screws 58 to the block 51 at the lowerjend of the casing 26, the inner sides of the said members being rabbeted to receive complemental formations on the outer faces of the arms of a U-shaped member 60. The inner faces of the arms of the U-shaped member 60 are rab-beted to receive complemental formations on the shank portion of'a T- The clutch may be arranged toshaped member 62, the ends of the head of which are arranged to engage the rabbets of the members 54 and 56. The members 54 and 56 are connected at theirforward ends by a bar 64, there being a space between the head of the andthe bar, as shown in Fig. 4, to permit 'movement of the .T-shaped member rela- T-shaped member ends of the driver passages 37 in the block 51. When the driversdescend to drive the tacks the T-shaped member may move relatively to the U-shaped member against the spring 66 to permit the passage of the tacks and drivers. The U shaped member 60 is held in longitudinal position by a dowel pin in thehlock 51 which enters a hole 72 in the member 60. The casing 26 and the tack holding mechanism just described are shaped peripherally to correspond substantially to the shape of the rear end of a shoe and hence, of course, to the shape of the shank piece which is to be inserted in the shoe. The shank engaging or lower face of the parts shown in Fig. 4 is preferably convexed and the co-operating face of the presser 4 concaved so that the shoe parts, including the shank piece and the sole which are clamped between them, will be given the proper exterior and interior contours desired for the inner and outer heel-seat portions of the shoe. I

In order to hold the shank piece tempo-- rarily in proper relation to the fastening inserting mechanism, clips 74, 7 5, 76 and 78 are provided. The clips 74, are similar in construction and are located one on each side of the fastening inserting mechanism and have inturned ends to engage below a shank piece at points adjacent to the breast line of the shoe. These clips 74 may be in the form of leaf springs secured by screws 80. The clips 74, 75 can therefore yield laterally to permit the shank piece, after its attachment, to be removed with the shoe. In order that the vertical pressure applied to the shoe by the support 4 may not dislocate'or bend the clips 74, 75, they are arranged for vertical bodily yielding movement. The screws 80 therefore do not attach the clips .74, 75 directly to the casing 26 but to a block 82(Fig. 6) arranged for vertical movement relatively to the casing, the amount of this movement being indicated by the space 83. The block 82 is held in place by a pin 84 passing vertically through the block 82 and held therein by a set screw 86, the projecting ends of the pin 84 sliding in holes in the casing 26. The block 82 is counterbored to'receive a spring 88 arranged on the pin'84 between the block 82 and the casing 26 which holds the block 82 in its lower position and permits the block and the attached clips 74, 75 to yield vertically to upward pressure. 'At the rear end of the casing 26 are similar clips'76 and 78 which may be formed as branches of a single spring member 89 secured at 90 to a part 91 arranged for slight vertical movement on the casing by collared screws 92, 92 passing through slots in the part 91 and threaded into the casing. A spring 94 is arranged between the part 91 and the casing to hold the part 91 andthe attached clips 76, 78 in lowered position. These/clips are arranged to engagethe shank piece substantially at the corners of the heel-seat as indicated in Fig. 5.

A pressing device is arranged to engage the rear portion of the shoe as it is brought into position to be operated upon and comprises a U shaped member 96 to engage the rear end of the shoe. The member 96 is mounted on a stem 98 arranged to slide forwardly and rearwardly in the frame 2 and held'in its forward position by a spring 100, V

its forward position being adjustably determined by nuts 102 threaded on the stem 98 and normally engaging the frame.

In the use of the machine the operator takes ashank piece 6 and introduces it by I endwise movement above the inturned ends of the clips 74, 75, 76 and 78, and against the lower face of the tack retaining mechanism, tacks having been fed to the tack pockets during a previous operation'of the machine. The operator then takes a shoe into which a shank piece is to be inserted and places it over theshank piece and the lower end of the fastening inserting mechanism and moves the said mechanism on the shaft 24 as a pivot and against thespring 28 to bring the shoe against the. pressing device 96 and over the presser 4. When the shoe engages the device 96 it is yieldingly pressed forwardly so that continued rearward movement of the shank piece andforce it against the tack inserting mecha nism and cause the shank piece, the sole of the shoe, and the parts located between them, to be firmly pressed together and given the proper heel-seat contour as de termined by the pressing faces. The handle 50 is then operated to cause power actuation of the cam 42, which acts upon the roll 40 on the upper end of the plunger 32, to cause the plunger and drivers'to be depressed and the tacks to be driven through the shank piece and into the shoe. The pressure of the support 4 is released, the shoe and casing 26 swung out, and the shoe and attached shank piece removed, the clips 74, 75, 76 and 78 yielding laterally to permit passage of the shank piece by them and being restored, of course, by their springs 88 and- 94 to lowered position to receive another shank piece.
